使用生成的图像作为在论坛中使用的链接

>我遇到了php图像函数，在生成后，我已经成功地用php创建了签名，如何让用户使用生成的图像作为其签名或w/e的链接？

 <?php
    $dest = imagecreatefromjpeg('test.jpg');
    $src = imagecreatefrompng('blade_02.png');
    imagealphablending($dest, false);
    imagesavealpha($dest, true);
    $black = imagecolorallocate($src, 0, 0, 0); 
    imagecolortransparent($src, $black);
    imagecopymerge($dest, $src, 17, 13, 0, 0, 60, 0, 0);
    imagecopymerge($dest, $src, 168, 70, 0, 0, 60, 100, 100);
    $font_black = imagecolorallocate($dest, 2, 1, 8);
    imagestring($dest, 3,357,19, "118" , $font_black);
    header('Content-Type: image/png');
    imagepng($dest);
    imagedestroy($dest);
    imagedestroy($src);
    ?>
